    Did some tests today with the 45mm -175mm lens on my Inspire 2 and was very impressed with the quality.
    I started wondering FOV wise how much tighter of a shot is the z30 camera over the 45mm-145mm lens.

    The z30 has a field of view of 63.7°(Wide) - 2.3°(Tele). Effective 1200mm

    The 45mm-175mm has a field of view of 27° Wide - 7.1° (Tele). Effective 350mm


    Doing some more digging the z30 only has an Effective resolution of 2.13 M.
    Where the x5s camera has an Effective resolution of 20.8MP.

    If you digitally zoomed in the 20mp photo from the 45mm-175mm to 2mp it would be around 3500mm.

    Where is the benefit of the z30? Just a bit closer live images I guess.

    I will be posting more photos for comparisons soon.

    Which 45-175, the F4.0-5.6 ASPH OIS Panasonic?

    How have you balanced it and does the X5S work the zoom & focus OK?

    At 210g it’s heavier than all of the DJI approved lenses.

    How have you balanced it?

    Thank you for the link but they seem very expensive!

    I might just purchase another 9-18mm balancing kit and add some extra lead weights to it to get it to balance.

    It is a bit more of an expense but it is worth the money because if it is not balanced correctly with this much weight it will ruin the gimbal of the camera.

    I am very interested in this. I have been wondering exactly the same thing but don't have the gear to do a comparison. If the 45-175 lens on the x5s camera gives comparable resolution when digitally zoomed and you dont need to zoom in live then the x5s could be a better option then the z30 depending on what you are using it for. I am looking forward to hearing more on your comparison.

    Stupid Question. (but I must ask)

    How does the back cap come off??

    I have only got the kit lens at this stage (I didn't realise that the 45-175 worked...) so haven't needed to remove the cap. (I have the balancing ring for the 15-45mm zoom lens, I intend to give that a go in the "near future")

    When I was first going through the datasheets and manuals, I "tried" to remove the back cap and it doesn't seem to want to come off.... (I haven't see anyone giving any hints on this.)

    Lots of people seem to just make some weights and velcro them onto the back of the cap..

    Simply twist it anti-clockwise to remove.

    Thanks for that hint, one other query..

    There is a balancing cap on as standard isn't there (there has to be because there isn't a bayonet fitting visible, as standard, but someone else on another thread cast doubt on that.....).

    Just hoping that I wasn't trying to yank the back of the camera off. lol.

    The rear cap is a screw fit, not bayonet but it is a standard part of the X5S.

    If you can’t see a thread at the rear of the camera body then the cap must still be on.

    Help please ...

    I have purchased the Panasonic 45-145 lens and balanced it but doesn’t seem to work reliably. Anyone have any suggestions?

    When I try to autofocus it takes about 10 seconds during which time the focus does not seem to change and it then puts a red a/f square up without actually focusing.

    When I try to calibrate the lens it fails most of the time but occasionally will complete the calibration but never actually says that the calibration was ok.

    In manual, the focus very rarely responds to the focus control. Occasionally the focus will ‘flicker’ and sometimes I get lucky and the image is in focus, however this process can take several minutes!

    The lens is on firmware version 1.3 and works perfectly on my Panasonic G7 camera.

    Has anyone else experienced this problem? At the moment the lens is pretty much unusable.
